The filming of
"Anger Management" had been pleasantly uneventful to this point -- aside from some some
Lindsay Lohan-related shenanigans, few reports of dustups on the set of the
Charlie Sheen-fronted sitcom have emerged as it plugs away at fulfilling its 100-episode order.

The key word there is "had," though.
TMZ reports Sheen and co-star
Selma Blair are at odds -- so much so that Sheen claims he "fired" Blair and says he won't work if she shows up to the set Monday (June 17).

The trouble started, according to TMZ, when Blair complained to the show's producers about Sheen's work habits on the show, saying he was frequently late and didn't work very hard when he was there. Sheen got wind of Blair's gripes and went off, going so far as to say she was fired. (Sheen has a financial stake in "Anger Management," but veteran producer
Bruce Helford is the showrunner).

TMZ also says Sheen now wants to offer
Mila Kunis -- who is dating Sheen's
"Two and a Half Men" replacement,
Ashton Kutcher -- as much as $1 million per episode to do an arc on the show. That sounds more like Sheen spouting off than a real offer -- no TV actor last season,
per this report, was pulling in seven figures per episode.

FX, which airs "Anger Management," referred
Zap2it's request for comment to Lionsgate, which produces the show. As of this post the studio hadn't responded.
